 `Tests\Feature\InvoiceNotificationTest` has been failing across every recent PR back to MS17 — past-due delivery assertions expect `queued` but observe `skipped`/`sent`. Diagnosed as CI environment / test reliability issue, not caused by any specific PR's changes. Falls within this phase's scope (notification surface audit) and **must be resolved before Phase 1 closes** — explicit user direction at MS19 PR merge.
 
+**Resolution:** Tracked and fixed via [#68](https://github.com/n8bar/CryptoZing/issues/68). First Issue under the M19 GitHub Issues trial (see milestone doc Decisions recorded).
